My Custom Mod Misadventure
Okay, I gave this a shot.
I used the Nexus Root Toolkit and rooting the thing went pretty well. I downloaded a Cyanogenmod rom, actually 2, and that was the start of my issues I think. I accidentally loaded the nightly instead of the stable.
I also didn't realize that adb would not boot anymore with 4.2.2 so I was stuck. I checked in the settings of the Nexus and it loaded up various roms you could use. I would select them and it would start to load, but then show the error message with the little android on his back.
I followed the tutorial "Root and Install CWM On Nexus 7 Running JB 4.2.2" in an attempt to get some control back and it went well until I was supposed to find the zip on the device. I had copied it over, separate from any folder, but I could not find it while in bootloader.
I ended up manually putting it in bootloader and using the Nexus Root Toolkit to restore the stock rom.
I liked certain things about the custom rom, but it was a pain not having the Google Apps, and I could not get the Gapps to install either.
Obviously I knew just enough to get halfway there. I am not sure when I will try this again, although I would like to learn more. I guess I better read some more tutorials on here.
